PETER J. BERDOH L, OF DELL RAPIDS, DAKOTA TERRITORY.

WAGON- SPRING.

SPECIFICATION forming part of Letters Patent No 286,377, dated October9, 188?,

Application filed February 20, 158 3. (No model.)

To all whom it may concern.-

Be it known that 1, PETER J. BERDOHL, a citizen of the United States,residing at Dell Rapids, in the county of Minnehaha and DakotaTerritory, have invented certain new and useful Improvements in\Vagon-Springs, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to springs for vehicles; and it consists in theconstruction, combination, and arrangement of the several parts, as willbe described, and pointed out in the claims. I

In the drawings, Figure 1 is an end view of awagon provided with myimproved spring. Figs. 2, 3, and 4 show in detail springs made of a sinle .s )rin -bar and Fi s. 5 6, 7 and a O 7 b 7 7 8 show springs made oftwo spring-bars, as will be more fully described.

The object of my invention is to provide a cheap spring, and onethat canbe readily.

made and. applied by a farmer or other persons, and will not need theaid of a mechanic.

In Fig. 1 I have shown my spring on a wagon.

udesignates the wagon-body, a the bolster, and a a side bars projectedupward from the ends of the bolster.

I) is the spring-bar, secured on block b, fixed on its under sidesmidway its length, and rested on the holster, as shown. I)' are boltsfixed on the upper side of the barb, near its ends, and providing restsfor the body (L.

b are slots formed in the ends of the bar I) and sliding over the barsa, whereby the spring is held in position. It will'be understood itmight be secured on the runninggear by bolts or otherwise; but I preferthe construction shown, as it is simple and convenient.

It is sometimes advantageous to use two or more blocks, 2), and securethem to the springbar in such manner that they maybe adjusted to andaway from the middle of the bar, so

that the length of bar free to spring will be increased or decreased asthe load is light or heavy. In order to do this I cut the opening I)through the bar I) and secure the block b to the bar I) by bolts 6passed through the opening I), and nuts If, so that the blocks 1) can beheld near the middle of the bar, as shown in full, or nearer its ends,as indicated in dotted, lines, Fig. 4. I

\Vher'e it is desired to have more spring than can be obtained by thesingle bar b, I employ the lower spring-bar, c, constructed with endslots, I), like the barb, and secured centrally to the said bar by thebolt 0, as shown in Figs. 5, 6, 7, and S.

c are blocks secured on the under side of the bar 0, directly under theblocks I), and adapted to rest on the bolster or other portionof therunning-gear on which the spring is placed. I

By this construction a simple, cheap, and durable spring is furnished.

By placing these springs on a lumber or other rough wagon and placingthe body on the springs, the wagon is converted at once into aneasy-riding spring-vehicle with but little trouble, and with as littletrouble the wagon can be changed from spring to rough for heavy hauling.

Lintend to make my springs of wood of suitable varieties, and itisdesigned with spewill be understood, however, that metal could beemployed where it is desirable to do so.

I \Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The vehicle-spring, substantially as described and shown, consistingof the bars 6 an d vided with the blocks b and constructed with theopening I), and theblocks 12, secured to the said bar by bolts b passedthrough the opening 1) and nuts 1), whereby the said blocks 7) may beadjusted to or away from the middle of said spring-bar, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
